In an analogous manner to general procedure IV, 1-(2-fluorophenyl)-1,3-dihydro-2,1,3-benzothiadiazole 2,2-dioxide (prepared in an analogous manner as described in general procedure I, 0.79 g, 3.0 mmol) was treated with cesium carbonate (1.46 g, 4.5 mmol) and but-2-yne-1,4-diyl dimethane-sulfonate (3.63 g, 15.0 mmol) to give 0.55 g of 4-[3-(2-fluorophenyl)-2,2-dioxido-2,1,3-benzothiadiazol-1(3H)-yl]but-2-yn-1-yl methanesulfonate.
